Sign with your finger or scan your signature off paper — vector-sharp at any zoom. Everything stays on your device: no account, no upload, no server. Two jobs, one app: sign the paperwork, then send the bill. Import a PDF, scan a paper contract or drop in a photo, sign it with a tap, and turn the same job into an invoice your client can pay in one scan. No account required. INVOICES AND ESTIMATES • Build an estimate, get it approved, convert it to an invoice in one tap • Your own numbering series, tax, per-line and whole-document discounts • Line items with quantities, units and a reusable price book • Attach job photos with captions, right on the document GET PAID FASTER • A payment QR on every invoice: PayPal, Revolut, Cash App and more • Mark sent and paid, and see at a glance what is still owed • Reminders before the due date, the day after, and a week later MAKE IT YOURS • Nine document styles, your own color, three type families • Fifteen page frames, from a plain rule to worked corners • Your logo, your details, your signature and stamp printed on every page SIGN ANYTHING • Draw your signature by hand and save it for reuse • Photograph a signature from paper and we clean it up for you • Add initials, stamps and a client approval block • Built-in scanner with edge detection and perspective correction ALWAYS SHARP Your signature is stored as true vector, so it stays crisp at any size, on screen, in the exported PDF and in print. No faded or pixelated marks. KNOW WHERE YOU STAND • Income and tax collected, by year and by quarter • Export the year to a spreadsheet in one tap MORE THAN ONE BUSINESS Run several trading names side by side. Each keeps its own documents, its own numbering and its own reports. PRIVATE BY DESIGN Everything happens on your device. Your documents are never uploaded to a server, so you can sign sensitive paperwork with real peace of mind. FAIR PRICING • Your first three documents are free, no card needed • With notifications on, we remind you before the trial ends • Cancel anytime in a single tap Premium is an auto-renewing subscription.
